I can hear it now! You are letting the cat out of the bag. By explaining computer forensic reports, you are aiding and helping computer criminals to cover their tracks.
But, there is always another side to an argument. By releasing this information, it can help people help computer forensic experts catch the criminals. Besides, people who commit computer crimes are very good at what they do. I am not releasing anything here they may not already know.
With that out of the way, let’s dive in.
What makes up computer forensics reports? Where does the information come from? Who puts them together?
Let’s start with the Who.
Computer forensics reports are prepared by computer forensics investigators. They gather the necessary information, analyze them and then draft out the final computer forensics reports. As good as they are, computer criminals oftentimes leave behind clues which aid the investigators to track down the root cause of their crime.
Even when the files have been deleted from the specific location in the computer, the original data is not at all erased from the entire computer system. With certain techniques, tools, and skills that the investigators are equipped with, the analysis of the fraudulent act or crime can be made with such accuracy.
Where does the computer forensic report information come from?
There are four main areas where the investigators gather their evidence from. There are other areas which are looked into but the following are the most commonly looked areas.
In order to detect illegal activities, the computer forensics analysts use the sophisticated tools and fully equipped laboratories to conduct thorough and accurate investigations.
For the law enforcement computer forensics specialist, a certain amount of extra care should be taken in collecting data and producing results, for the standard of proof is higher. There are advantages on the data collection end, however. For once a court has authorized a search warrant, an officer (and possibly several) with badge and gun can go seize the defendant’s computer by surprise and by force. Once the computer has been seized and imaged, all data is accessible and may result in additional charges being brought against the defendant.
By contrast, in a civil case, there tends to be a lot of negotiation over what computers and what data can be inspected, as well as where and when. There is not likely to be any seizing of computers, and quite a long time may take place between the time the request to inspect a computer is made and the time the computer is made available to be inspected. It is common for one party to have access to a very limited area of data from the other party’s computer. During this time, a defendant may take the opportunity to attempt to hide or destroy data. The author has had several cases wherein the computer needed for analysis was destroyed before the plaintiff had the opportunity to inspect. Such attempts at hiding data are often discovered by the digital forensic sleuth, who may in turn present evidence of such further wrongdoing in expert witness testimony.
Opportunities for learning techniques and interacting with other professionals may differ as well. While some computer forensic software suites and training, such as Access FTK, EnCase, or SMART Forensics are available to most who can pay, others, such as iLook are available only to law enforcement and military personnel. While many support and professional organizations and groups are available to all, some, such as the High Technology Crime Investigation Association (HTCIA) are not open to professionals who provide for criminal defense (with a few minor exceptions).
The Advantages and Disadvantages about Computer Forensics
Posted by 0845 Telephone Numbers in Computer on March 11th, 2010
Computer forensics has become an important of litigation. Computers have become an important part of your lives. This does not exclude criminals who have the technical know how of hacking into computer network systems. Electronic evidence has played a role in court but obtaining can be difficult. There have been issues of authenticity concerned with this type of evidence. Nonetheless it still used today with the help of legal standards to make them admissible in court. Computer forensics is beneficial but it also has disadvantages. Computers are the most dominant form of technology. It has been used in variety of purposes which has made digital and electronic evidence important. However there are still setbacks to this field.
Computer forensics’ main advantage is its ability to search and analyze a mountain of data quickly and efficiently. They can search keywords in a hard drive in different languages which is beneficial since cyber crimes can easily cross borders through the internet. Valuable data that has been lost and deleted by offenders can be retrieved which becomes substantial evidence in court. Legal professionals are able to produce data in court that were previously impossible.
The exchange of information is taking place everyday over the internet. Although this may be convenient for us, it can also pose as an opportunity for criminals. Phishing, corporate fraud, intellectual property disputes, theft, breach of contract and asset recovery are some of the situations wherein computer forensics can be used. Apart from the technical aspect, legal issues are also involved. Computer forensic analysts make their investigation in such a way that the electronic evidence will be admissible in court. There are advantages and disadvantages when it comes to computer forensics. This field is relatively new and criminal matters usually dealt with physical evidences. This makes electronic evidence something very new. Fortunately it has been a helpful tool wherein important data needed for a case that has been lost, deleted or damaged can be retrieved.

Using Computer Forensics Training in the Real World
Posted by 0845 Telephone Numbers in Computer on December 4th, 2009
Sadly, if you look at the number and types of crime committed in the past 10 years, it is easy to understand why more people are needed in criminal justice careers. Most crimes include assault, car theft, home intrusion, and so on but another area that is becoming a serious problem and costing companies around the world millions of dollars is computer crime. To lower incidences and bring criminals to justice, colleges are now offering a wide range of computer forensics training.
Typically, people that have interest or better yet, experience in the world of law enforcement or criminology are usually the ones that excel in working computer crimes. This field is necessary and exciting, which is why we see so many new students taking classes. Computer forensics training covers a broad range of topics, some that include identifying computer hackers, locating data hidden on hard drives, and more. In addition to criminals being found, proprietary information that could wreck havoc on companies is also protected.
The computer forensics classes that are necessary for a career such as this are diverse. You will gain incredible knowledge such as the techniques that are used for data recovery specific to encrypted and deleted computer files. Along with this, computer forensics training will also teach you how to identify illegal activity, no matter how small the evidence. After all, computer hackers notoriously leave subtle hints behind on computer hard drives. By using the appropriate tool and/or software program you will have the skills needed to find these pieces of evidence that might otherwise be forever lost.
While computer hackers know how to get into computer systems and clean up behind them, they always leave traces of information that can be detected using computer forensics. You would have training in state-of-the art software programs and tools so deeply hidden information could be found and then used as evidence. With this, the hacker could be prosecuted with the hard evidence you discovered.
The type of computer forensics training you will complete depends on the type of career interested in. These classes have different levels, with the first requiring that you have basic understanding, or preferably, experience with the Windows Operating System. The second level of training would take you through to a degree in computer science.
What is Computer Forensics?
Posted by 0845 Telephone Numbers in Computer on December 4th, 2009
Computers have radically changed the way we live your lives. Everyday living as become easier and technologically advanced decades ago. It has changed the way we work and the way we live in our houses. Children to day are sometimes even more technologically aware than their parents. Mobiles phones have gotten smaller and laptops have gotten slimmer.
With the launch of the Iphone that used the touch screen technology it will only be a matter of time when this idea permeates into other devices and appliances. Unfortunately, technology also makes it easier for criminals to their dirty job. However, computer forensics makes sure that technology is put to lawful use.
Crime and computers
We have seen a lot of Hollywood movies about hackers stealing from financial institutions. We have also seen two parties making their deals through bank transfers with a bunch of computers. Although these are not possible in real life, there are other ways that criminals can use computers.
Computer forensics is basically applying computer science to assist in the legal process. It entails the technological and systematic inspection of the contents of a computer system for evidence. Individuals in this field are called by different titles such as digital media analyst or computer forensics investigator. These people scanned a computer thoroughly to find out if they have used for a civil wrongdoing or criminal act.
The first task of the computer forensic investigator is to find sources of documentary or digital evidence. The next step would be to preserve the evidence so that it could be analyzed later on. When dealing with computer systems, important files or data can be quickly lost.
The investigator should take the necessary test because data retrieval can be time consuming and costly. The investigator would then analyze the collected data for potential and supportive evidence. The final step would be presenting the findings. The investigator will render his opinion based on the examination and make a report.
Computer technology has changed the way we live, work, and for others – commit crime. Although the internet may seem like a very convenient place users should always be wary for seemingly innocent offers.

Computer Forensics – DLL Errors – How to Remove DLL Errors on Startup
Posted by 0845 Telephone Numbers in Computer on December 4th, 2009
EnCase Computer Forensics Demo
Have you ever encountered a problem with C:/WIND/SYSTEM32.UKWIEG96.DLL message pop-up on start-up? Or other kinds of similar DLL Error messages appeared when you start PC system? This article will show you how to fix and avoid such error message in the daily use of your computer. With the 4 easy ways as below, you can quickly master the methods of removing DLL errors.
Like the old saying that to a hammer everything looks like a nail, then to a victim, everything begins to look suspiciously like an attack. When there are actual bogeymen around, every sound makes a person jump. Let’s take on a few of the suspects.
Her computer told her that it was recovering orphaned files and security descriptions, replacing bad clusters and bad logfiles, and fixing unreadable security. All are signs of problems, but are messages generated by Windows’ own repair programs, Chkdsk and Scandisk, and aren’t openings for an intruder to walk into the computer unopposed.
Anther scary Norton message read, “NIS is protecting your connection to a newly detected network on adapter “WAN (PPP/SLIP) Interface”. But this was just the program reporting on the computer’s own wide area network adapter and Internet access being enabled.
She noticed that an oddly named program called “Wild Tangent” seemed to be active. Turns out that Wild Tangent is a game network company. It is pretty active in using the computer’s network resources, and puts a lot of advertisements on the user’s computer. But as bothersome as some find it, it comes preinstalled on many computers, including the Teacher’s Dell. Not a likely avenue for remote control by an unauthorized user.
Our little heroine even learned to use Netstat (stands for “network statistics”). Netstat displays network connections, statistics, routing tables, and more juicy info. Linux users can directly invoke it. Windows users can bring it up through a DOS box (command shell) by clicking on “Start” then “Run”, then typing in “CMD”, and finally “netstat” in the window that comes up. Mac users can invoke it by first bringing up the “Terminal” available in the Utilities that come with a Macintosh. But netstat can bring up a screenloads of hard-to-understand information. Try it yourself with various switches (like “netstat -a” or “netstat -p”). Hers was unalarming to a jaundiced but practiced eye.
How to fix DLL Errors?
Method 1: a.Click ” Start” menu–”Run”–type in “regedit”. b. Delete these registry keys as below manually:
HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRun
Method 2: Some DLL files would be infected by virus or Trojan. If the anti-virus program on your computer detects and deletes those infected files, you would probably receive error message alarming you that some dll files can not be found. You absolutely will fail to run the relevant applications or programs but keep receiving DLL error message on the startup. In such situation, you have to re-download and install those application to re-register the dll information. So here comes the instruction to disable an application run automatically on system startup in order to avoid such DLL error message:
a. Click ” Start” menu–”Run”–type in “msconfig”—Start— select the certain item to disable.
b. Reboot your computer.
If you feel hard to do this then you can try some registry cleaner programs to disable those startup applications on your computer.
Professional people search sites pay a lot of money to get the background information, cell phone numbers and other needed information so they can meet your needs. They succeed when you succeed. So, start your search today and protect your business and your family

The Potential Of Computer Forensics Training
Posted by 0845 Telephone Numbers in Computer on December 4th, 2009
Computer crimes have become common occurrences these days, and the alarming rates of criminal activity on IT systems has led to a higher demand for experts in the field of computer forensics. In fact, statistics and the job growth rate for the last five years will prove that computer forensics is one of the professional domains with the most promising careers. This is why so many educational institutions have created special programs for computer forensics training so that more people can be able to work and collect legal evidence to be used in court against hackers, and thus contribute to the protection of corporate assets and the preservation of good company reputation.
There are very many types of courses included in the category of computer forensics training; they teach students how to recover deleted files, encrypted or intentionally hidden data, but also show trainees the dark side of computers. Traces always remain behind after illicit computer activities, but with the help of forensics tools and softwares, you’ll be able to detect them and recover the data you need. Depending on the program, the educational institution and the objective of the courses, the duration of computer forensics training could even take years. There are also some admittance conditions for people eager to become specialists in such applied sciences.
Depending on the level for which the computer forensics training is performed, requirements may differ greatly. While for certain cases, knowledge of the Windows Operating System is enough, for others, very professional computer training is required. Thus, only applicants with a BA in computer science may be accepted for computer forensics training. In case you have experience with information security or you’ve worked as a network or Windows administrator, you can also qualify for certain levels of training. Some computer forensics training programs even provide toolkits at the completion of the courses for those who get certification.
This means that someone who gets certification, is in fact authorized to perform forensic investigations that are admitted in courts of law. Getting computer forensics training may be a nice decent profession with a good revenue. While some experts get to work for smaller or larger businesses, others manage to get to the top of intelligence levels and deal with national security problems. What needs to be mentioned here is that only the best of the best get in such positions, and the road up there is really paved with challenges and tons of hard work.
